Description
Technical Field
The invention relates to the field of printing and dyeing waste gas treatment, in particular to a dandelion-like floccule adsorption device for printing and dyeing waste gas.
Background
The waste gas of textile printing and dyeing industry mainly comes from two main aspects: the spinning process of chemical fiber, and the pretreatment and functional after-finishing processes of textiles.
Taking the spinning process of viscose fiber chemical fiber as an example, raw materials need to be made into spinning solution, and a large amount of carbon disulfide needs to be added in the process of making the spinning solution, so that harmful gas substances mainly comprising hydrogen sulfide, carbon disulfide and sulfur dioxide are released in the spinning processing process.
The heat setting machine treatment is an important part of the textile pretreatment process. During heat setting, various dye assistants and coating assistants on the textile are released, so that a large amount of VoCs (volatile organic compounds) are released at the outlet of the exhaust pipeline finally. The organic gases are mainly formaldehyde, polyphenyl, aromatic hydrocarbons and other organic gases. In the functional after-finishing process of the textile, waste gas mainly comes from two links. In the hot-melting dyeing process of the polyester disperse dye, a certain micromolecular dye is sublimated into waste gas and is discharged due to high temperature. The non-ironing and flame-retardant finishing of the cotton fabric is carried out through a baking link, and due to the addition of some chemical additives, the phenomenon that aldehyde gases such as formaldehyde and the like and ammonia gas are released during baking can occur.
Because the particularity of weaving, contain a large amount of flocculent impurity in the printing and dyeing waste gas, flocculent impurity adhesion nature is strong, though easily filtered the interception, nevertheless equally because its adhesion nature, easy card leads to the filter screen of filter assembly to be very easily blockked up, is difficult to the clearance, leads to in prior art, need regularly pause the processing progress of low printing and dyeing waste gas to change the maintenance to filter assembly, lead to the whole treatment effeciency to printing and dyeing waste gas to influence very big.

Referring to fig. 4, the dandelion-like end 83 includes a plurality of multi-branch draped needles fixedly connected to the connecting block 82, the multi-branch draped needles include an extension connecting needle 831 fixedly connected to the connecting block 82 and a hair needle 832 connected to an end of the extension connecting needle 831, the plurality of hair needles 832 are interlaced and distributed to effectively increase the density of the whole hair needles 832 and further effectively ensure the intercepting effect of the hair needles on the flocs in the exhaust gas, the hair needles 832 include a plurality of branch single needles, referring to fig. 5-6, the connecting points where the plurality of branch single needles are close to each other and the end of the extension connecting needle 831 are fixedly connected with magnetic hemisphere 10, the two magnetic hemispheres 10 are attracted to each other, the arrangement of the two magnetic hemispheres 10 can make the hair needles 832 and the extension connecting needle 831 have a structure convenient to disassemble, thereby facilitating the exchange of the hair needles 832 intercepting the flocs to be saturated, when the flocs intercepted by the hair needles are saturated, the two-way filter screen can be turned upside down by controlling the electric rotating shaft to rotate 180 degrees, and then air can be introduced between the taraxacum intercepting hemisphere and the selective permeable filter screen 7 through the air inlet pipe 31, due to the existence of the floccule, the permeability of the plurality of hair needles 832 is poor, at this time, under the impact action of the gas, the hair needles will gradually fall off downwards and fall on the bearing net plate 4, at this time, the fallen hair needles 832 can be recovered through the sealing door 5, meanwhile, the end part of the extension connecting needle 831 is adsorbed with a new hair needle 832, so that the effect of replacing and cleaning the dandelion type intercepting hemisphere is realized under the condition of not stopping the waste gas treatment process, the treatment efficiency of the whole printing and dyeing waste gas is obviously improved, it should be noted that, when gas is introduced, the introduction speed of the gas needs to be kept lower than that of the waste gas, so that the situation that the counterweight blocking ball 73 floats under the action of the gas below is effectively avoided.
Referring to fig. 7, the branch single needle includes an intercepting needle 92 fixedly connected to the magnetic hemisphere 10 and an intercepting capsule 91 connected to an end of the intercepting needle 92, the outer end of the intercepting capsule 91 is connected to a plurality of intercepting burrs 11 uniformly distributed, and the intercepting burrs 11 can effectively increase a contact area between the hair needle 832 and the floccule, so as to effectively increase an intercepting effect of the hair needle 832 on the floccule.
Referring to fig. 8-9, arrows in the drawings indicate the flowing direction of the exhaust gas passing through the selective permeable filter screen 7, a plurality of vertical special-shaped holes 71 and horizontal passages 72 are drilled in the selective permeable filter screen 7 and are distributed alternately, the vertical special-shaped holes 71 and the horizontal passages 72 are communicated with each other, counterweight plugging balls 73 are placed in the middle of the vertical special-shaped holes 71, one ends of the two selective permeable filter screens 7 close to each other are of a mesh structure, one ends of the two selective permeable filter screens 7 far away from each other are of a solid structure, when the exhaust gas passes through the selective permeable filter screen 7 located above, the exhaust gas can sequentially pass through the vertical special-shaped holes 71, the horizontal passages 72 and the mesh structure to enter between the two selective filter screens 7, and at this time, the exhaust gas performs a penetrating extrusion effect on the counterweight plugging balls 73 in the selective filter screen 7 located below to plug the column vertical special-shaped holes 71, when waste gas enters the transverse channel 72 through the vertical special-shaped holes 71 and the net-shaped structure, the waste gas cannot pass through the blocked vertical special-shaped holes 71 to enter the lower part of the selective permeable filter screen 7, so that the waste gas filtered by floccules can be discharged only through the outlet pipe 22, and the phenomenon that the waste gas is not easy to leak when the dropped hair pins 832 are subjected to centralized treatment and replacement through the sealing door 5 is effectively avoided.
Through the setting of the dandelion formula interception hemisphere on the two-way filter screen, can realize the high-efficient interception to the flocculus in the waste gas, thereby effective protection is selected penetrating filter screen 7 and is difficult for blockking up, simultaneously after the flocculus saturation of interception on the multi-branch drapes over the needle, the position is upside down about the control two-way filter screen, can ventilate between the dandelion formula interception hemisphere and the penetrating filter screen 7 of selection through advancing pipe 31 through ventilating this moment, this moment under the impact action of gas, because the permeability variation, hair needle 832 can drop gradually and the separation of the dandelion formula interception hemisphere, the change is retrieved to the hair needle 832 that drops to the realization through sealed door 5, the realization is not changing the effect of clearing up to the dandelion formula interception hemisphere under the condition that need not stop the waste gas treatment process, show and improve the holistic treatment efficiency of printing and dyeing waste gas.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
